The color of the lake of Annecy is just incredible.
The day was a bit grey but the sun came in the afternoon making the lake looks like if it was lighted !
@randystreat I’ve done some research for you : the lake of Annecy is turquoise blue due to calcite , but it’s true that it is fed by a river that comes directly from the mountain, very pure, plus the absence of algae … so you’re true !
